Note from Dave (June 2014):
"Latest info (June 2014) on their their web site states:
'Vegan Fish friendly beer
Both our bottled beer and our cask beer are suitable for vegetarians and vegans. This is because we do not use isinglass to clear our beer.'"

Company email:
"All our beers are vegan – all of them, including the Dining Ales. The labels say Vegetarian and Vegan".

Company email:
"All our beer is veggie, vegan & organic. it is bottle-conditioned, and non-filtered."
